Patients with heart failure engage in a delicate balancing act all year round, taking care not to drink too much liquid because the weakened heart muscle cannot cope with excess fluid. But what is a person supposed to do during those blast-furnace days of July and August? Perspiration depletes the body of fluids and electrolytes, such as potassium, that are needed for proper heart function. The patient, who is typically also taking a diuretic to excrete excess fluid, then feels the need to drink more water.

Solar panels generate electricity by absorbing sunlight, but that is only half the battle. Once electrons in the panel are energized, they must be channeled in the same direction - a process that typically requires a panel made with layers of two kinds of material. Not in the future, if a team of researchers from the University of Pennsylvania and Drexel University can help it. In a new study published online by the journal Nature, the scientists reported they had created a new class of ceramic material that could accomplish both tasks cheaply and efficiently.

MICHAEL JORDAN has been fined by the NBA for making comments about the league's ongoing collective bargaining process. NBA spokesman Tim Frank yesterday confirmed the penalty for the Charlotte Bobcats owner, but said the league doesn't comment on the total. ESPN.com reported the fine was $100,000. In an interview last month with Australia's Herald Sun, Jordan said the NBA's current model was "broken" and called for revenue-sharing for small-market teams such as his Bobcats and the Milwaukee Bucks, whom Australian Andrew Bogut plays for. Jordan added that he knows "owners are not going to move off what we feel is very necessary for us to get a deal in place where we can coexist as partners.

Study questions theory of diet for poor, supermarket proximity Poor people would have healthier diets if their neighborhoods had more supermarkets and fewer fast-food outlets - or so many community and public health activists argue. But a new analysis led by University of North Carolina researchers suggests this "food environment" theory is too simple. Using data from a heart disease study that followed 5,115 people in four cities for 15 years, the researchers correlated fast-food consumption and diet quality with proximity to fast food, supermarket, and grocery stores.

Dried fruit in the pantry is always money in the bank, but the qualities of shriveled apricots, raisins, cherries and their kin seem even more valuable in the winter months. I mean, aside from booze-mummified fruitcake made when the Beatles were on stage. It is now that nuggets of desiccated fruit pop up more frequently in all manner of dishes. They add color and sweetness to desserts, muffins and quick breads. In savory recipes, dried fruit does that and more: It provides depth of flavor by balancing acidity, spiciness and saltiness.

Talk about a dose of reality. Even though I had heard rumors, the public notice from the state printed in the newspaper last Wednesday was a shocker. Potassium iodide tablets are being offered to residents within 10 miles of the nuclear power stations in Ocean and Salem Counties. As I read the notice, I thought back to that day many years ago when my husband and I took Frank and Sarah Sauers, our friend's elderly parents, on a sightseeing tour of some of the remaining wilderness of South Jersey.

Worrying about nuclear disaster seemed an unlikely thing to be doing on a sunny summer afternoon in this sleepy farm town. But Joanne Gross, her husband and granddaughter in tow, said she wasn't taking any chances. "We're at war," Gross said grimly, scooping up three tiny, silver-wrapped pills that officials hope will keep her family safer in the event of a nuclear accident or attack. "We have to do everything we can to be safe. " This weekend, New Jersey began the first of six sessions aimed at preparing residents for the worst.

I am tasting salt for the first time. After years of coveting its crystalline crunch on pretzels, its salty flocking on popcorn and chips, I am here with several shakers and I'm tasting the stuff, straight. Kosher salt, iodized salt, free-flowing table salt, purified crystals of sea salt, potassium salt, reduced-sodium salt, pretzel salt, and several varieties of raw sea salt lie on plates across my kitchen counter. Some are as coarse as gravel, while others are powdery fine. They differ in color, moisture content, transparency, flavor, and, most surprisingly, aroma.

The U.S. Army Humvee, the back doors of its camouflage facade swung open to the chill, sat yesterday in the crowded parking lot of the Vivra Renal Care Center of Philadelphia, in West Philadelphia. Inside, where the battle was being fought, National Guardsmen in green Army fatigues carried Emethel Dunbar, 61, on a stretcher and lay her on a reclining chair, next to a lifesaving dialysis machine. She had already missed one of her thrice-weekly sessions because no one could get through the snow piled high in front of her home on Hazel Street, just blocks from the center.
